I wrote to you with the phone. Item update. Feedback. But not sure if got my message. With the latest firmware version 20161018 model A8 MAX Serial X562L2ZH6A100023 happen fatal error with microSD! Have formatted microSD firms Transend class 10 (premium) 32 GB as internal memory. After reboot was removed all moved app! Tried to return as external drive, so phone has correctly formatted her! Sections all left, but no more on one device not read microSD. No formatting neither Linux, Windows neither did not help (even low-level). Please fix the error and give compensation for spoiled the flash drive. Thanks
